Mbh 1.89.4a

“Yayati replied to this, ‘It is said that sin destroyeth the merits of four virtuous acts. Vanity containeth the element of that which leadeth to hell. The virtuous never follow in the footsteps of the vicious. They act in such a way that their religious merit always increaseth. I myself had great religious merit, but all that, however, is gone. I will scarcely be able to regain it even by my best exertions. Beholding my fate, he that is bent upon (achieving) his own good, will certainly suppress vanity. He who having acquired great wealth performeth meritorious sacrifices, who having acquired all kinds of learning remaineth humble, and who having studied the entire Vedas devoteth himself to asceticism with a heart withdrawn from all mundane enjoyments, goeth to heaven. None should exult in having acquired great wealth. None should be vain of having studied the entire Vedas. In the world men are of different dispositions. Destiny is supreme. Both power and exertion are all fruitless. Knowing Destiny to be all-powerful, the wise, whatever their portions may be, should neither exult nor grieve. When creatures know that their weal and woe are dependent on Destiny and not on their own exertion or power, they should neither grieve nor exult, remembering that Destiny is all powerful. The wise should ever live contented, neither grieving at woe nor exulting at weal. When Destiny is supreme, both grief and exultation are unbecoming. O Ashtaka, I never suffer myself to be overcome by fear, nor do I ever entertain grief, knowing for certain that I shall be in the world what the great disposer of all hath ordained. Insects and worms, all oviparous creatures, vegetable existences, all crawling animals, vermin, the fish in the water, stones, grass, wood--in fact, all created things, when they are freed from the effects of their acts, are united with the Supreme Soul. Happiness and misery are both transient. Therefore, O Ashtaka, why should I grieve?
